A baseball has mass 0.145.kg
1) if the velocity of a pitched ball has magnitude 45m/s and the batted ball's velocity is 55m/s in the opposite direction, find the magnitude of the change in momentum of the ball and the impulse applied to it by the bat.
b) If the ball remains in contact with the bat for 2.00ms, find the magnitude of the average force applied by the bat
The change in momentum...
p(final) - p(initial) = ...
This solution provides a brief calculation for finding change in momentum using mass and velocity as well as an equation for force.
